Each of the chains 12 and 1.3 has the hooked link 16 on its end for attaching the two ends of the chain 12 and 13 to one onother. The l'tOOliK'l. links 16 have the ends 1'? and 18 turned as shown to engage the loop of the acl iacsnt enrl link. The end I? is made sligl'itly longer than the 1862itenoiiiig down :1, s gztcsd distzmos from 2.1116

along tho link so that the owl of tho 1 link to'b'e ongagod themin can be tippotl at an :mglo orig; bonooth the longer oncl 17 and thereby he slipped onto the two ends 17 and 18,botl1 suds having lioltlin engogo moot on the links attached, therefiy firmly attaching the two links so that as they :llO prsssscl against the side of the time they can not disengage from one another or-bo (lisongagerl by any pullingstmin upon the chain from running over tho roadway.

The central chains" 19 soul 20 are prefsnably made with e common quarter twist link, tho two chains 19 211111720 being attochsil. to oils i'lilOtllQli at Spaced distances by tho interlooking of tho links of tho acljooont chains, shown at 21. The two o Joins 19 and 20 are arranged in tho dim moncl shops formation by the connection of the said chains 19 and 20 to the side chains 12 ztlltl 13 about tho conter of the distance between the @Ol'lIlQCtEfl links 21. The com motion of the side chains 12 and 18 is profot'ably atl'oinool throughout the length of the chain by means of a beveled link 22 which has a curved and 23 and at the other end the beveled end 25 with the raised end portion 24% for engagement into a link of the side chains .12 or 13. The raised end 924 S0 adjusts or arranges each of the links 22 that they lie flat, as shown inFig. 8, against the side of the tire l1 and permits the link of the chains 12 or 13 to slide freely back and forth in the raised and 24, at the same time providing av our'vocl and 23 into which the links of the chains 19 or 20 may be easily 1' l'iSOl'l-Ml thereby assembling the entire all sin.

'llho ends of mo chains 19 and 20 are attached toe no another and. to the side chains preferably by means of o hooko i link The to be inserted in the link 26 and between the hooks 27, which hooks 27, as shown in Fig. 9, extend down nearly to the flat side of the link 26, thereby forming a very secure and firm holding link- 26 for the attachment of the two end links 28 to the side links of the side chains 12 and 13.

It often happens that a greater gripping capacity is desired for the chains than that which is normally PIOVldGC l; Accordingly, I have arranged for a removably attached cross chain 29 which. is preferably made of the quarter twist links, the same as the central chains 19-and 20 and has attached to 27 in one end, which link can be quickly and easily inserted in the links of the chains 19.

and 20 to which the link 22 is attached, as

' shown in Figs. 1 and 4, thereby providing a detachable cross chain which may be inserted whenever it is desired to increase the of chain, that is, the two side chains 12 and 13' and the center chains 19 and 20, the two center chains .bein'g' each shaped in the zigzag form by attachment alternately to one another and vto the side chains thereby forming the diamond shape pattern around the tire. 11.' Thetwo forms of hooks 16 and 26 are substantially equivalent to one another, form 16 being used with the sidechains be- .cause of the ease of attaching the same and with .whichit holds, and the the securit form 26 being used for the sure and perfect attachment of the center chains 19 and 20' t0 the side chains 12 and 13.

gripping capacity of the chain upon the I claim as new I 1. In a tire chain,'a pair of side chains, a pair of continuous central chains, said central chains having the links thereof connectcd with each other, and links to secure the central chains to the side chains, said links having sides connected by curved .wardly and then downwardly and merging into the other side to provide a pointed nose slidably receiving the links of the side chains.

2. In a tire chain, a pair of side chains, a single pair of unitary, central chains extending throughout the circumference of the tire, said certral chains being continuous and undulating and having the links of their inwardly extending parts extending longitudinally of the tire and directly interconnected to form a series of antiskid parts at spaced intervals throughout the periphery of the tire, and means to secure the outwardly extending parts of the central chains to the side chains.

3. In a tire chain, a pair of side chains, a pair of unitary central chains extending throughout the circumference of the tire, said central chains being continuous and undulating and having the links of their inwardly' extending parts directly interconnccted to form a series of anti-skid parts at spaced intervals throughout the periphery of the tire, and means to secure the outwardly extending parts of the central chains to the side chains.

In testimony whereof I have affixed my signature in the presence of two witnesses.
